RELATED APPLICATIONS

[0001] This is a continuation-in-part of U.S. patent application Ser. No. 10 / 768,408, filed Jan. 30, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 322,024, filed Dec. 17, 2002, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 290,571, filed Nov. 8, 2002.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to signal transmission and detection, and in particular, to techniques for compensating for signal distortions caused by signal dispersion and nonlinearities within the signal transmission media.

[0004] 2. Description of the Related Art

[0005] Signal processing architectures for intersymbol interference (ISI) equalization as used for communications transmission and / or storage systems may be divided into two categories: discrete-time architecture and continuous-time architecture. Discrete-time architectures, commonly used in current systems, use a sampled approach t...
